Abstract

PURPOSE:To prevent the outflow of refuse and dusts to the downstream side of a dust collector body even when any abnormality is generated in an injection pipe. CONSTITUTION:A support member 19 is disposed faced oppositely to a disc 18, and a transverse member is mounted between the disc and the support member, thus constituting a framing body 17 with an opening section 21. A screen 22 is installed onto the outer circumference of the framing body 17 while a rake 23 is set up inside the screen 22, and a dust collector body 24 is turned in the direction of raking-up C while injecting water from nozzles 33. Even when the supply of water is stopped from the nozzles 33, refuse, mud, etc., taken into the opening section 21 are confined in the dust collector body 24, and do not flow out to the downstream side.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust remover provided in a water channel such as an irrigation channel and a drainage channel.

[0002]

2. Description of the Related Art Conventionally, as a dust remover for removing dust such as irrigation canals and rivers, for example, a net screen dust remover such as Japanese Utility Model Publication No. 59-34583 is known. As shown in FIG. 5, this dust remover is provided with a drive sprocket 2 on the water surface via a rotary shaft 1 and a driven sprocket 4 via a rotary shaft 3 in the water channel A. The net screen 5 is arranged via a chain (not shown). Then, by the motor 6 connected to the drive sprocket 2, the net screen 5 is rotated to prevent the passage of water dust and the like on the upstream side while flowing out the water to the downstream side, so that the net screen 5 is captured. Dust, mud and the like are dropped by the water jetted from the jet pipe 7 onto the receiving portion 8 to be removed.

[0003]

In the above-mentioned prior art, for example, the injection port of the injection pipe 7 is clogged,
Alternatively, when the supply of water to the jet pipe is stopped for some reason, dust, dirt, etc. captured on the net screen 5 do not fall onto the receiving portion 8 and directly adhere to the dust removing machine main body downstream. There was a problem that it was carried and discharged, and the dust removal function was not fulfilled at all.

Therefore, the present invention solves the above problems and
An object of the present invention is to provide a dust remover capable of preventing dust and debris from flowing out to the downstream side of the dust remover main body even when some abnormality occurs in the injection pipe.

[0005]

According to the present invention, there is provided a frame body having a substantially cylindrical shape and having an opening on one side thereof for taking in dust and the like, a screen provided on the outer periphery of the frame body, and an inside of the screen. The dust eliminator main body includes a rake to be mounted and is horizontally rotatable, and a jet pipe for jetting water onto the screen.

[0006]

With the above construction, even if some abnormality occurs in the injection pipe, the dust is confined inside the main body of the dust remover by the screen provided on the outer periphery of the frame body, and is prevented from flowing out to the downstream side.

The frame body 17 includes a circular plate 18, a support member 19 formed in a ring shape and facing the circular plate 18, and a plurality of lateral members arranged between the circular plate 18 and the supporting member 19. Member 20
Due to the above, the opening portion 21 for taking in dust etc. is formed on the upstream side of the water channel A. A reticulated screen 22 is stretched around the outer periphery of the frame body 17, and the rake is provided by each lateral member 20.
By mounting 23 toward the inside of the screen 22, a dust remover main body 24 including the frame body 17, the screen 22, and the rake 23 is configured. Further, the shaft 13 is fixed to the center of the disk 18 by the cylinder 25 and the pressing member 26, whereby the dust remover main body 24 is provided so as to be horizontally rotatable about the flow direction B of the water channel A as an axis center.

A plate-shaped holding member 27 is provided on the upstream side of the water channel A,
An angle member 28 having an L-shaped cross section is provided so as to extend in the width direction, and a receptacle 30 having a draining screen portion 29 having a plurality of holes formed on the bottom surface thereof is provided on the holding member 27. Is provided. Further, between the draining screen portion 29 and the inside of the frame body 17, a dust receiving portion 31 having a substantially U-shaped cross section is provided.
Is fixed on the angle member 28, and the dust receiving portion 31
Is provided such that the base end on the inner side of the frame body 17 is inclined upward with respect to the horizontal.

Reference numeral 32 denotes an injection pipe which is disposed on the dust remover main body 24 and has a horizontally long slit-shaped injection hole 33 facing the screen 22. A water supply pipe 34 is connected to substantially the center of the injection pipe 32, and the water supply pipe 34 is connected to a discharge side 35A of a single motor-equipped pump 35. A suction pipe 36 is connected to the suction side 35B of the pump 35, and the tip of the suction pipe 36 is arranged in the water channel A.

Reference numeral 37 is a reinforcing member fixed to the outer circumference of the disk 18, and a partition plate 40 is fixedly mounted on the outer side of the reinforcing member by a bolt 38 and a washer 39 so that the outer circumferences of the partition plate 37 and the disk 18 are fixed.
